It is also the primary component of the Halotron I fire-extinguishing mixture. Its ozone depletion potential is ODP = 0.012, and global warming potential is GWP = 76. HCFC-123 will eventually be phased out under the current schedule of the Montreal Protocol. It was discontinued in new HVAC equipment in 2020 in developed countries but will still ...
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br.It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers.

Halotron I was originally introduced in 1992 as a replacement for Halon 1211(bromochlorodifluoromethane), a substance known for its significant ozone-depleting properties. While Halon 1211 has a global warming potential (GWP) of 2,070, [ 2 ] Halotron I's GWP is considerably lower at 77, reflecting a 96% reduction in environmental impact.
Warning sign for fire suppression system Civilian Halon 1301 fire extinguisher, USA, 1980s. Halon 1301 was developed in a joint venture between the U.S. Army and Purdue University in the late 1940's, [5] and became a DuPont product in 1954.
Taco Bell. In the 1970s Taco Bell was bought by PepsiCo, and by the 1980s the chain had announced it would offer free soda refills. That made it the first eatery to declare an official bottomless ...
Clean agents extinguish fire by displacing oxygen (CO 2 or inert gases), removing heat from the combustion zone (Halotron I, FE-36, Novec 1230) or inhibiting the chemical chain reaction (Halons, Halotron BrX). They are referred to as clean agents because they do not leave any residue after discharge, which is ideal for protecting sensitive ...
